Can laser eye surgery cause migraines​?

Many people who think about laser eye surgery want to know about possible side effects. One question that sometimes comes up is whether laser eye surgery can cause migraines.

Migraines can affect daily life and may cause strong headaches, light sensitivity, or visual changes. If you already experience migraines, it is normal to wonder whether eye surgery could make them worse.

At IVISION LASER in Adelaide, we believe it is important for patients to have clear information before making decisions about their vision. In this article, we explain what migraines are, how laser eye surgery works, and what patients should know.

This information is general in nature and does not replace advice from a qualified health professional.

What is a migraine?

A migraine is a type of headache that can cause strong pain. Some people also experience nausea, sensitivity to light, or visual disturbances. Migraines can affect people in different ways. Some people have migraines often, while others only experience them occasionally.

For some individuals, migraines may begin with visual symptoms. These symptoms are sometimes called a visual aura. A person may see flashing lights, zigzag lines, or blind spots before the headache begins¹https://www.mayoclinic.org/diseases-conditions/migraine-headache/symptoms-causes/syc-20360201#:~:text=A%20migraine%20is%20a%20headache%20that%20can,that%20it%20interferes%20with%20your%20daily%20activities. .

Many factors can trigger migraines. These may include stress, tiredness, certain foods, dehydration, or hormonal changes. Vision problems can also contribute to headaches for some people²https://www.mayoclinic.org/diseases-conditions/migraine-headache/symptoms-causes/syc-20360201#:~:text=A%20migraine%20is%20a%20headache%20that%20can,that%20it%20interferes%20with%20your%20daily%20activities. .

What is laser eye surgery?

Laser eye surgery is used to correct refractive errors. Refractive errors affect how light focuses inside the eye. Common refractive errors include short sightedness, long sightedness, and astigmatism³ https://www.nhs.uk/tests-and-treatments/laser-eye-surgery-and-lens-surgery/ .

During laser eye surgery, a laser reshapes the front surface of the eye. This surface is called the cornea. Changing the shape of the cornea helps light focus more clearly on the retina. The retina sends visual signals to the brain, allowing you to see clearly⁴ https://www.nhs.uk/tests-and-treatments/laser-eye-surgery-and-lens-surgery/ .

The goal of laser eye surgery is to reduce dependence on glasses or contact lenses for some people⁵ https://www.nhs.uk/tests-and-treatments/laser-eye-surgery-and-lens-surgery/ .

Can laser eye surgery cause migraines?

There is no clear evidence that laser eye surgery directly causes migraines.

Migraines are complex and may be linked to many different factors. They are usually related to how the brain processes sensory signals, including light and visual information.

Laser eye surgery changes how light focuses in the eye. For most patients, this change helps improve vision⁶ https://www.nhs.uk/tests-and-treatments/laser-eye-surgery-and-lens-surgery/ .

Some people may notice temporary visual changes during the healing period after surgery. During this time, the eyes are adjusting as they recover.

If someone is already prone to migraines, it is possible that certain visual changes or light sensitivity may trigger a headache. However, this does not mean the surgery⁷ https://pmc.ncbi.nlm.nih.gov/articles/PMC10293021/ itself caused the migraine condition.

Temporary visual changes after surgery

After laser eye surgery, it is normal for the eyes to take time to heal. During the early recovery period, some people notice temporary visual changes⁸ https://www.verywellhealth.com/lasik-surgery-long-term-care-4847046 .

Vision may appear slightly blurry for a short time while the eye surface heals. Some patients also notice glare or halos around lights at night during early recovery ⁹ https://www.verywellhealth.com/lasik-surgery-long-term-care-4847046 .

These effects usually improve as healing continues.

If someone is sensitive to bright light, these changes may feel uncomfortable at first. Wearing sunglasses and following aftercare advice may help during the healing period.

Your eye doctor will monitor your recovery and answer any questions during follow up visits.

Headaches and vision problems

Some headaches are linked to vision problems rather than migraines.

For example, eye strain can cause headaches in some people. This can happen when the eyes work harder to focus.

People who wear glasses or contact lenses sometimes experience headaches if their prescription is not correct. For some patients, clearer vision after laser eye surgery may reduce eye strain ¹⁰ https://pubmed.ncbi.nlm.nih.gov/34241701/ . However, experiences vary from person to person.

Your eye doctor will assess your vision and discuss what may be suitable for your eyes.

Why a full eye assessment matters

A detailed eye examination is an important step before considering laser eye surgery.

During this assessment, the eye doctor checks your eye health and vision. They also ask about your medical history.

If you experience migraines or frequent headaches, it is important to mention this during your consultation.

This information helps your doctor understand your health history and answer your questions more accurately.

Not everyone is suitable for laser eye surgery. A full assessment helps determine whether treatment may be appropriate for you.

What to expect after laser eye surgery

Most patients return to normal activities fairly quickly after laser eye surgery. However, recovery can vary from person to person.

Your doctor will provide aftercare instructions to support healing. This may include using prescribed eye drops and attending follow up appointments.

Some patients experience temporary dryness or light sensitivity during recovery. These symptoms usually improve over time.

If you experience ongoing discomfort, vision changes, or headaches after surgery, it is important to contact your clinic for advice.

Your care team can review your symptoms and guide you on the next steps.

Setting realistic expectations

When considering laser eye surgery, it is important to understand both the benefits and the limitations.

Laser eye surgery aims to correct refractive errors and improve vision for some patients ¹¹ https://pubmed.ncbi.nlm.nih.gov/34241701/ . Results vary depending on individual eyes and prescriptions.

The procedure does not prevent other health conditions, including migraines.

Your eye doctor will explain what laser eye surgery may be able to achieve based on your specific situation.

Clear information helps patients make informed decisions about their eye care.

When to seek advice about headaches

If you experience frequent or severe headaches, it is important to seek medical advice.

Headaches can have many possible causes. An eye examination may help identify whether vision issues are contributing.

Your eye health professional may also recommend speaking with your general practitioner if migraines are affecting your daily life.

Working with the right health professionals can help you better understand and manage your symptoms.

Take the next step

If you are considering laser eye surgery, learning about the procedure and recovery process is an important first step.

Questions about migraines and vision are common, and discussing them with an eye care professional can help you feel more confident about your options.

Every person’s eyes and health history are different. A proper assessment is the best way to understand what may be suitable for you.

Take the suitability self-test to learn whether laser eye surgery may be an option for your eyes. This quick step can help you explore your vision correction options.
